Question

How should the conditions be changed to prevent the volume of a given gas from
expanding when its mass is increased?
Temperature is lowered and pressure is increased.
b
Temperature is increased and pressure is lowered.
Temperature and pressure both are lowered.
d
Temperature and pressure both are increased

Answer 1

Answer:

a .Temperature is lowered and pressure is increased

c. Temperature and pressure both are increased

d. Temperature and pressure both are decreased

V= nRT/P

If we increase n then for keeping V to be constant the ratio T/P needs to decrease and it can be achieved by three methods:

Temperature and pressure both are decreased

Temperature and pressure both are increased

Temperature is lowered and pressure is increased
